<h3><u>Answer;</u></h3>
Dilute solution
One gram of salt in 100 liters of water could be considered a <em><u>dilute solution</u></em>.
<h3><u>Explanation</u>;</h3>
- <em><u>A solution is a mixture that is composed of two or more substances. It is formed when one substance (solute) dissolves on another called solvent. </u></em>
- Solutions are homogeneous mixtures as the substances in it are always in the same phase. <em><u>A solution may be concentrated or dilute depending on the amount of solute or solvent in the solution.</u></em>
- <u>A dilute solution has more solvent that solute while a concentrated solution has more solute than the solvent. In this case, </u><em><u>a solution containing 1 g of slat which is the solute in a 100 liters of water is an example of dilute solution.</u></em>
Answer:
yes you will need a control
Explanation: all i know is that you need a control i don't know how to set it up lol sorry
Answer:
it appears to be B. acceleration
Answer:
Reflects
Explanation:
A metal spoon looks very shiny because its surface is very smooth, which is why it acts like a mirror and reflects light very well.
Rocket thrust equation
= ( mass flow rate of fuel burnt ) X (Velocity of gas ejected ) + ( Exit Pressure - Outdoor Pressure ) X ( Area of exhaust )
In this case, we can assume the exit pressure = outdoor pressure and since area of exhaust is not given, it can be assumed to be negligible.
In this case, by Newton 3rd’s law,
Force exerted by gas on rocket
= Force exerted by rocket on gas
= (10kg/s) X (5 x 10^3 m/s)
= 5 x 10^4 N
